RALPH JACKSON, OF ALTRINCHAM, ENGLAND.

SELF-PROPELLED VEHICLE.

SPECIFICATION formngplt Of Letters Patent N0. 660,192, dated. OctObel23, 19O. Application filed June 4,1900. Serial No. 19,031; (No model.)

To all whom it may concern,.- Y

Be it known that I, RALPH JACKSON, a subject of the Queen of GreatBritain and Ireland, and a resident of Altrincham, England, (whosepost-office address is the Motor Cycle Works, Altrincham,) have inventeda certain new and useful Improvement in Self-Propelled Road-Vehicles,(for which I have applied for patent in Great Britain, No. 17,902, datedSeptember 5, 1899,) of which the following is a specification. Y

This invention relates to certain improvements in the construction ofself-propelled road-vehicles.

In the accompanying drawings, Figure 1 is a side view, Fig. 2 is a plan,and Fig. 3 is an end view, illustrating a motor-tricycle according tothis invention. Fig. l is a plan of the steering arrangements.

The vehicle has two leading wheels A by which it is steered, and atrailing wheel B, which is the driving-wheel.

The main framework of the vehicle comprises two main tubes C C, whichextend from front to rear and which are connected by two cross-tubes DE. The forward ends of the tubes C are inclined outwardly from the pointwhere they are joined by the tube E, and on tne extremities of theseinclined ends are provided head-lugs or ball-heads F, which receive thesteering-columns G, and from these steering-columns project the axlesupon which the Wheels A are mounted. The head lugs F are braced by thestays H. The secondary or seat frame comprises a pair of bent tubes P,supported upon springs Q, which are attached to the lowerstay H and tothe projecting ends of the cross-tube E. Carried by the upper part ofthisframe is a reservoir R, which contains oil or spirit for the engine,and secured to the seat-arms S is a Ysecond reservoir T. The seat properis formed by upholstery carried onl and suspended between these tworeservoirs. Flexible tubing connects the engine N with the reservoir Rand the reservoir R with the reservoir T. The contents of the reservoirT may be forced into the reservoir R by air compressed by atire-inflater.

The steering-heads F are inclined backward, so that when the wheels Aare steered to right or left they incline in the direction in which theyare steered, as indicated by dotted lines in Fig. 3.

Projecting at right angles from the steer# ing-columns are the axles ofthe wheels A, and at right angles to each axlev is a lever Z, the endsof the two levers Z being coupled by a rod J, so that bothsteering-columns turn together. The steering is effected by the lever K,which is connected by a rod L to the lever M, Which extends inward fromone of the axles.

The vehicle is driven by the engine N, the shaft of which drives acounteishaft O, which is connected by differential speed-gear to thedriving-wheel B, as shown in Figs. l and 2. The exhaust-gases of theengine pass into a receiver V and thence into the cross-tube E andultimately escape by holes along the under sides of the main tubes C. Asocket in the middle of the cross-tube D receives the inclinedpillar-tube for the rear seat, and the top of this tube is connected bya pair of diagonal stays to the rear ends of the tubes C.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In combination a primary frame comprising the tubes C connected bycross-tubes D, E, and disposed parallel with each other from the rearwheel to the tube E from whence they diverge to the steering-heads Fwhich are braced by stays H, a frame for the back seat being carried onthe cross-tube D and on the rear ends of the tubes C, and a frame forthe front seat comprising the tubes P, arms S, reservoirs R, T, saidseat-frame being supported on springs carried on the cross-tube E and onone of the stays H, substantially as described. A

2. The front seat-frame, consisting of a pair of bent tubes P havingtheir upper ends attached to the reservoir R and linked to the upperends of springs Q, and having their lower parts carried on the lowerends of the springs Q, a pair of seat-arms S attached to the tubes P andcarrying a reservoir T which with the reservoir R supports theupholstery of the seat proper, substantially as described.

In witness whereof I have hereunto set my hand and affixed my seal inpresence of two witnesses.
